What is the hardness of our drinking water?

The hardness is determined by the amount of calcium in the water.
NTMWD's water is considered moderately hard. To determine the hardness
of the water measured in grains per gallon refer to the water
quality reports and divide the total hardness
by 17.12. Read the hard water facts sheet for more information.

What causes the taste and/or odor changes during the summer months?

Taste and/or odor changes are due to a naturally occurring event,
an algal bloom. An algal bloom exists when conditions
such as temperature of the lake water, nutrients, and sunlight
are optimum for algae to reproduce. As a result of the algal
bloom, taste and odor changes occur. The event is a palatability
issue and does not change the high standard for water quality.
